Title Progressive loss of PGC-1alpha expression in aging muscle potentiates glucose intolerance and systemic inflammation
Organism Mus musculus
Experiment type Expression profiling by array
Summary Decreased mitochondrial mass and function in muscle of diabetic patients is associated with low PGC-1alpha, a transcriptional coactivator of the mitochondrial gene program. To investigate whether reduced PGC-1alpha and oxidative capacity in muscle directly contributes to age-related glucose intolerance, we compared the genetic signatures and metabolic profiles of aging mice lacking muscle PGC-1alpha. Microarray analysis revealed that a significant proportion of PGC-1alpha-dependent changes in gene expression overlapped with age-associated effects, and aging muscle and muscle lacking PGC-1alpha shared gene signatures of impaired electron transport chain activity and TGFbeta signalling.
Overall design Gastrocnemius muscle mRNA from young (10 week old) and old (24 month old) wild-type and knock-out (muscle-specific PGC-1alpha, myogenin-cre) C57Bl/6N/6J/129 mice
